Boost controlled washer pump (don't laugh it's a real problem)
Ok, this is going to sound funny at first, but here is the issue. I have a supercharged 944 running about 12-psi boost. So I am installing the ERL H2O injection system to help with in cylinder cooling even beyond the aftermarket intercooler I have. So I have mounted a 5-gallon collapsible water jug in the rear cargo pocket, run a water line to the engine compartment to the pump. Now the way the ERL system works is that under boost a pressure switch is activated and supplies a certain amount of resistance to the pump to turn it on. My problem is that the water tank sits lower then the pump in the engine compartment so I need a secondary pump to get the water to the injection pump. So ERL recommends a washer pump, cheap item. But they also recommend that’s it's boost activated! How in the world will I pull this off! I am one step away from selling this whole project for a 951!
